Administrative Spatial Edits and Notes:

Spatial and population data for the main Island of Mauritius is for administrative level 3. However, due to lack of spatial data for other islands, the same level of detail could not be employed for the surrounding areas. The Island of Rodrigues, however, was added at administrative level 2. This was done via coastline data (built in to polygons) extracted from the NOAA coastline extractor (http://rimmer.ngdc.noaa.gov/coast/getcoast.html). Arbitrary administrative IDs were assigned (unique per island in the group surrounding Rodrigues) and the population was assigned to the main island only.
